How do solar screens work?
The majority of sunlight striking an unprotected glass window passes through into the home, and a small percentage is reflected. Solar screens dramatically reduce the amount of sunlight striking the window. Most of the sun’s heat is absorbed or reflected by the screen and carried away by convective air currents created by the warm screen. This diagram shows a window with SunTex installed. In midsummer as much as 230 BTUs can fall on an unprotected square foot of glass.
